scripts: Remove bar animations from vol/brightness
Removed the ascii-art bar animations calculated for e.g. dunst
notifications for the controls of brightness and volume.

The dunst notifications finally have a working bar slider built into
them when invoked with the correct stack option.

# Brightness control script using xbacklight
# Will use notify-send to create brightness notifications, if dunst is used
# or the notification daemon supports tag stacks, will automatically update
# the same notifications and not create new ones.
